Underwater Habitat


In many situations, a permanent base for operations underwater could be very useful, for example: for research, underwater “farming”, protection of sea environment, construction under water taking a long time, etc. Such base – a Habitat, able to support relatively long term living of workers, who sometimes need to work on shore, and other times need to work underwater, should be reliable and comfortable. The Habitat should be close to the shore, but under weather. Supplying of it should not require use of ships. Ability to move between a workplace deep underwater and the Habitat should not depend on tides and storms.


The Building

    The underwater waterproof construction – the Building does not need glass windows, unless it is also used for entertainment. External cameras and hydrophones plus internal screens and speakers should provide enough information about external environment.

As in a submarine, it should be possible to shut off different sections of the Building in case of leakage.

The Building needs a few “transition chambers”, which could be filled with water or emptied, as needed. These chambers should be used to bring some underwater vehicle into the building, empty the chamber of water and transfer people and cargo into the building. They should be used in a reverse order to move people and cargo out of the Building.


Worker Submarine

    Worker Submarines (see “Working under Water” on this site), are well suited for use in conjunction with such Building. They should use “transition chambers” to get in and out of the Building.


Climbing Elevator

    A Climbing Elevator (see “Climbing Elevator” on this site), with some adjustments, should be sufficient to move people and cargo between this Building and the shore.

    The Climbing Elevator consists of

·        a water proof cabin with “limbs”, which has its own engine,

·        a sturdy “construction”, usually made with pipes, with a channel in it, the waterproof cabin of this Elevator moves grabbing special elements of this “construction” – a “ladder”.

The cabin “climbs” through this construction.

The shape of this “construction” depends on the relative location of two endpoints of the Climbing Elevator - the Building below and the place on shore above, to which the Building is connected via the Elevator.

Waves, usually, should not be able to reach the endpoint on shore. The other endpoint in the Building should be the “transition chamber”.

  The construction could be curved and could have intermediate support elements, attached to the ground.

  The cabin moves through air and through water, hence it needs to carry fuel and compressed air for its engine. Supply of compressed air and fuel is done on shore.


Power Supply

Electric cables in the water are dangerous. Hence, power for the use in the Building, should be generated on shore and passed using Hydraulic Transmission to the Building (see “Hydraulic Transmission” on this site). Generally speaking, the pump on shore should move hydraulic fluid through Hydraulic Transmission, which ends in the Building underwater. Compensating machines of such Transmission, as electric generators and compressors, should be in the Building, where they provide electricity and provide supply of compressed air, which is often needed underwater.


Fresh Air Supply

    Fresh Air should be perpetually pumped into the Building from the shore through the system of pipes. A similar system should pump out exhaust air. Air compressors should be on shore.

    Similar system should provide supply of high pressure compressed air for Worker Submarines and Climbing Elevator, when needed.


Fresh Water Supply

    Fresh Water should be supplied through the system of pipes from the shore. This water should be also used to supply Worker Submarines.


Fuel Supply

    Fuel to supply Worker Submarines and Climbing Elevator, should be provided through a system of pipes from the shore.


Garbage Removal

    Garbage should be compacted and moved on shore in plastic bags, using Climbing Elevator, for processing or disposal on shore.



    Sewage should be disinfected and pumped using sewage pipes deep into the sea, far from the Building.


Emergency Evacuation

    Emergency Evacuation should be done with Climbing Elevator, Worker Submarines and other equipment supporting breathing, while under water.
